Turn the lens counterclockwise while pressing the camera’s lens release button. Detach the lens once it has stopped turning.
Please refer to the camera’s instructions for details.

• Set the camera’s power switch to OFF when attaching or detaching the lens.

• When the power switch of the camera is set to OFF, the focus lens pushed forward is automatically stored.* Do not detach the lens until the lens is completely stored.

• After detaching the lens, place the lens with the rear end up and attach the dust cap to prevent the lens surface and contacts from getting scratched. Make sure the lens and dust cap mount indexes are aligned when attaching the dust cap.

• Contacts that are scratched, soiled, or have fingerprints on them may result in faulty connections or corrosion, which may lead to malfunctions. If the contacts get soiled, clean them with a soft cloth.

• When the lens storage is set to ON on the camera.

Focusing/control ring

The focusing/control ring can be used as either a focusing ring or a control ring.

Use as a Focusing Ring
Set the focusing/control selector switch to FOCUS. Set the focus mode (AF/MF) using the camera’s menu.
To shoot in autofocus (AF) mode, set the camera’s focus mode to AF.
To use only manual focusing (MF), set the camera’s focus mode to MF, and focus by turning the focusing ring (focusing/control ring).

• This lens does not have a focus mode switch.

• Delayed focus may occur if the focusing ring (focusing/control ring) is quickly turned.

• Do not touch the operating part in the front of the lens while the focus lens is operating. If external pressure is applied to the moving part, the lens initialization may be performed to return the focus lens to the correct position for control purposes.

• The lens’ focusing ring (focusing/control ring) is electronic.

• It is possible to set cameras that support electronic fulltime manual focusing to constant manual focusing when the camera is in the operational mode. However, the camera settings need to be changed.

• When AF operation is set to [ONE SHOT], manual focus is possible after autofocusing has been completed by continuing to press the shutter button halfway. However, the camera settings need to be changed.
  Please refer to the camera’s instructions for details.

Focusing/control ring
The focusing/control ring can be used as either a focusing ring or a control ring.

Please refer to the camera’s instructions for details on how to use the control ring.

Hood (Sold separately)

The custom lens hood reduces unwanted light that causes flare and ghosting and protects the front of the lens from rain, snow, and dust.

Align the red attachment position mark on the hood with the red dot on the front of the lens, and then turn the hood in the direction of the arrow until you hear a click.

Detaching the Hood
Keep your finger pressed down on the button located on the side of the hood, and then turn the hood in the direction of the arrow until the attachment position mark on the hood is aligned with the red dot on the front of the lens to detach it.
The hood can be reverse-mounted on the lens for storage.
